To simplify the expression \( \frac{12^{53}}{7^{53}} \) using the properties of exponents, specifically the quotient rule, we can rewrite it as follows:
\[ \frac{12^{53}}{7^{53}} = \left(\frac{12}{7}\right)^{53} \]
This uses the property of exponents that states:
\[ \frac{a^m}{b^m} = \left(\frac{a}{b}\right)^m \]
So, the simplified form of \( \frac{12^{53}}{7^{53}} \) is:
\[ \left(\frac{12}{7}\right)^{53} \]
